Silicones are inert, synthetic compounds with a variety of forms and uses. Typically heat-resistant and rubber-like, they are used in sealants and cooking utensils, just to name a few. Their characteristics include:
- Low thermal conductivity
- Low toxicity
- Thermal stability
- The ability to repel water and form watertight seals
- Does not stick to many substrates, but adheres very well to others, e.g. glass.
- Does not support microbiological growth
- They have high gas permeability
